How the Kia RIO holds up with age

Every car fails the MOT more often as it gets older. What matters when you are buying is how steeply that happens for this particular model. These are the 2025 pass rates for the Kia RIO grouped by the vehicle's age at the time of the test.

Age at test Tests Pass rate
3–5 years10,65391.21%

11 years and over48,89166.36%

The Kia RIO drops 24.9 percentage points between its early years and the 11-plus bracket, which is a steep decline. On an older example, the MOT history is worth reading closely before you buy.

Why the Kia RIO fails its MOT

Across every Kia RIO that failed its 2025 MOT, the most common area of failure was brakes, accounting for 21.44% of all recorded failure items. These are the areas worth having checked before you buy, and worth budgeting for on an older example.

How the Kia RIO compares

Ranked on pass rate, the Kia RIO sits 409th of 651 models in this data , and 11th of the 16 Kia models covered . Kia as a whole averaged 79.69%, so this model runs 3.8 points behind its own brand average.

What this means when buying a used Kia RIO

A pass rate is a population average, not a verdict on the specific car in front of you. The average Kia RIO came to its 2025 test at 65,787 miles and 10.4 years old. Most examples tested were petrol, though 18.46% were diesel.

The useful check is the individual car's own MOT record: how many times it has failed, what for, and whether advisories keep reappearing. A recurring advisory on corrosion, suspension or brakes tells you far more than a model-wide average, and a mileage that does not move consistently between tests is a warning in itself.
